multi room sets
trying to run another set in br from same box[SERIES 4] using an hd splitter and 50' of hd cable. its not working.
i've purchased 2 tivo's in the last 4 yrs & now they want me to buy another tivo unit plus another extender for$230. + $60. a yr on top of the $190. i'm spending now.
has anyone had any luck running 2 sets off of 1 box? ir repeater for remote working great.
i've seen some ideas with series 2&3 but not 4's.

I'd agree that it's probably the distance of your HDMI cable. I have a similar setup. Make sure you've got a high quality HDMI cable with the lowest AWG rating you can get. 50 feet is pushing it. One thing you can try is to reduce the TiVo's output down to 480i and see if you get a signal that way, then slowly move your output up till you get a cutoff of signal.
